What Preparation Is Needed Before Steel-Look Windows Are Fitted?

t436-22

Before Belgian steel-look profile windows are fitted, the opening must be measured accurately, cleared and checked for level and plumb, and the surrounding finishes should be protected. Confirming access, power and the installation schedule in advance also helps the fitting go smoothly.

Confirm the Measurements Before Production

Steel-look windows are made to measure, so the most important preparation step is an accurate on-site measurement. Our team measures the opening during a visit, and the written specification and drawing are then approved by you before anything goes into production.

Please make sure the opening is ready to be measured. Plaster, tiles or old frames that are still being removed can change the final size, so it is best to finish those works first or agree on the dimensions in writing.

Once the drawing is approved, changes become harder and slower, so review every detail carefully.

Prepare the Opening and the Wall

The opening should be clean, square and free of loose material. Remove old frames, sealant, debris and any damaged plaster around the edges. A stable, sound surface gives the new frame a firm base.

Check that the opening is level and plumb where possible
Remove loose render or crumbling masonry
Note any cracks, damp patches or structural concerns

If the wall needs repair, complete it before the installation day so the frame can be fixed properly.

Plan Access, Space and Handling

Steel-look windows and doors are heavy, precisely made elements, so the installation team needs safe access to the opening and enough room to bring the units inside. Clear furniture, rugs and personal items from the area, and make sure pathways and stairwells are not blocked.

If the work is on an upper floor, let us know in advance so the correct handling equipment and safety measures can be planned. Keep children and pets away from the work zone during the fitting.

Protect Floors, Furniture and Nearby Surfaces

Fitting windows creates dust, debris and sometimes small splashes of sealant or mortar. Protecting the rooms in advance saves cleaning time and prevents damage.

Cover floors with protective sheets or cardboard
Move furniture and fragile items away from the opening
Cover nearby walls, radiators and shelves
Remove curtains, blinds or wall decorations that may be in the way

Check Utilities and Surrounding Elements

Before installation day, check whether there are shutters, blinds, electric wiring, air conditioning pipes or drainage lines near the opening. Let us know if any of them need to be relocated or taken into account in the design.

If you plan to fit shutters or external blinds, confirm this at the design stage so the frame and fixings are planned correctly. Good coordination between the window, the wall and any other trades avoids delays.

Agree on the Schedule and Final Checks

Agree on a clear installation date and time window with the team, and confirm who will be home to receive the crew and approve the finished work. It is useful to ask about the sequence of works, especially if other trades such as painters or tilers need to follow.

On the day, walk through the completed windows with the installer. Check operation, locks, seals and the finish, and note anything that needs adjustment before the team leaves.

Frequently asked questions

How far in advance should I start preparing for window installation?

Start as soon as the design is agreed, so the measurement, drawing approval and production can be planned in order. Clear the opening and arrange access shortly before the fitting date.

Do I need to be at home during the installation?

It is recommended, so you can receive the crew, answer questions and check the finished work together. Someone should also be available to confirm any last-minute decisions.

Can the windows be fitted while I still live in the apartment?

Yes, in most cases the works can be done while the home is occupied, as long as the work area is cleared and protected. Let us know your situation so the process can be planned around your daily routine.

What if the opening is not perfectly straight?

Minor irregularities are normal and are usually handled during installation with proper fixing and sealing. If there are larger issues, we will point them out during the measurement so they can be addressed before production.

Common mistakes to avoid

Many homeowners finish plastering or tiling after the windows are measured, which can change the opening size. Leaving furniture and access routes blocked is another common cause of delays on installation day.

Our recommendation

Before the measurement visit, take photos of the opening from inside and outside and note any wall damage or obstacles. Finish any structural or plaster repairs first, then approve the drawing in writing so production starts from confirmed dimensions.

Summary

Good preparation means accurate measurements, a clean and sound opening, protected rooms, clear access and an agreed schedule. These steps help Belgian steel-look windows be fitted safely, accurately and with minimal disruption.
